Network-manager-applet is a system tray applet which lets you easily
connect to different networks. It is created for GNOME's notification area
but it also works for other desktop environments which provide a system
tray like KDE or XFCE. It displays the available networks and allows to
easily switch between them. For encrypted networks it will prompt the user
for the key/passphrase and it can optionally store them in the
gnome-keyring.
